Description

Technical Field

[0001] The present invention relates to the technical field of tungsten steel mold processing, and specifically relates to a deburring device and method for tungsten steel molds with an anti-spray function. Background Technique

[0002] A mold is a tool that makes a blank into a workpiece with a specific shape and size under the action of external force, and is widely used in blanking, die forging, cold heading, extrusion, powder metallurgy part pressing, pressure casting, and the compression molding or injection molding of products such as engineering plastics, rubber, and ceramics. Among them, molds made of tungsten steel have a service life that is dozens of times that of ordinary steel molds. Tungsten steel molds are widely used because of their high hardness, high strength, corrosion resistance, high temperature resistance, and small expansion coefficient. After the tungsten steel mold is processed, it needs to be deburred.

[0003] Currently, the existing deburring method for tungsten steel molds is usually to clamp and fix them with a bench vise and for personnel to hold a grinding device to perform deburring operations on them. This method not only increases the workload of personnel, but also causes the debris generated by deburring the tungsten steel mold to splash everywhere. For this reason, we propose a deburring device and method for tungsten steel molds with an anti-spray function. Summary of the Invention

The pressure sensor is bidirectionally electrically connected to an external PLC controller. By setting the pressure sensor, the clamping force is sensed.

[0016] A processing method of a tungsten steel mold deburring device with an anti-spray function includes the following steps:

[0017] S1: Place the mold to be processed on the surface of the support grille, and then start the second motor to rotate the bidirectional screw to drive the two moving blocks to move towards each other, so that the two turntables move towards each other to clamp and fix the tungsten steel mold to be processed. At this time, the pressure sensor real-time feeds back the clamping pressure to the control system. When the value of the pressure reaches the threshold reserved inside the external PLC controller, the external PLC controller automatically turns off the second motor;

[0018] S2: After the tungsten steel mold to be processed is clamped and fixed, start the first motor to drive the grinding wheel to rotate. During the rotation of the grinding wheel, input the processing trajectory of the grinding wheel into the external PLC controller, and then start the robotic arm to control the rotating grinding wheel to perform multi-angle grinding on the surface of the tungsten steel mold according to the preset processing trajectory to remove burrs;

[0019] S3: After deburring the surface of the tungsten steel mold to be processed, control the four electric telescopic rods to contract so that the support grid moves downward away from the tungsten steel mold, and then start the third motor to rotate the turntable on the right to drive the tungsten steel mold to rotate. When the side of the tungsten steel mold to be polished rotates to the upper side, turn off the third motor, and then control the four electric telescopic rods to reset so that the support grid supports the tungsten steel mold again. After the support, control the robotic arm to work again to drive the grinding wheel to move and polish the unpolished side of the tungsten steel mold;

[0020] S4: After the grinding is completed, stop all power components, and then control the second motor to reverse so that the two turntables move away from the processed mold after grinding, and the mold can be removed;

[0021] S5: During the grinding process, start the air extraction pump to create a negative pressure environment in the storage box. The flying debris generated by grinding is filtered by the barrier net and retained in the storage box. After the grinding is completed, pull the pull rod forward so that the two pull ropes move to drive the two clamping posts away from the two clamping holes, and then the storage box can be taken out. After removal, the residue generated during the grinding process inside it can be cleaned up.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows: The deburring device and method for tungsten steel molds with anti-spray function have the following advantages:

[0023] 1. Through the linkage design of the air extraction component and the storage component, a negative pressure environment is formed during the grinding process. The air extraction pump actively adsorbs the flying debris, and after being filtered by the barrier net, it is centrally stored in the detachable storage box. This structure not only effectively prevents the debris from flying and polluting the environment, but also avoids the health hazards of the debris to the operators in traditional manual operations. At the same time, it simplifies the cleaning process, significantly improving safety and environmental protection;

[0024] 2. By using the coordinated control of the robotic arm and the PLC controller, the grinding trajectory can be preset and deburring operations with multiple angles and high precision can be achieved. Combined with the third motor in the rotating component driving the turntable to rotate, it supports the automatic flipping of the tungsten steel mold. Cooperating with the electric telescopic rod to adjust the height of the support grid, multi-sided continuous processing without manual intervention is realized, greatly improving the processing efficiency and consistency;

[0025] 3. The moving component drives the moving blocks to synchronously clamp through the bidirectional screw, and combines with the pressure sensor to monitor the clamping force in real time. When the pressure reaches the preset threshold, it automatically stops, which not only ensures the stable fixation of the mold, but also avoids damage to the mold caused by over-clamping. The turntable with anti-slip groove design further enhances the clamping stability and is suitable for processing molds of different sizes. BRIEF DESCRIPTION OF THE DRAWINGS

10. The processing method of a deburring device for tungsten steel mold processing with splash-proof function according to any one of claims 1-9, characterized in that: It includes the following steps: S1: Place the mold to be processed on the surface of the support grid (32). Then start the second motor (85) to rotate the bidirectional screw (83) to drive the two moving blocks (82) to move towards each other, so that the two turntables (94) move towards each other to clamp and fix the tungsten steel mold to be processed. At this time, the pressure sensor (11) real-time feeds back the clamping pressure to the control system. When the value of the pressure reaches the threshold reserved inside the external PLC controller, the external PLC controller automatically turns off the second motor (85); S2: After the tungsten steel mold to be processed is clamped and fixed, start the first motor (25) to drive the grinding wheel (22) to rotate. During the rotation of the grinding wheel (22), input the processing trajectory of the grinding wheel (22) into the external PLC controller. Then start the robotic arm (23) to control the rotating grinding wheel (22) to perform multi-angle grinding on the surface of the tungsten steel mold according to the preset processing trajectory to remove burrs; S3: After the burrs on the surface of the tungsten steel mold to be processed are removed, control the four electric telescopic rods (31) to contract so that the support grid (32) moves downward away from the tungsten steel mold. Then start the third motor (93) to rotate the right turntable (94) to drive the tungsten steel mold to rotate. When the unpolished side of the tungsten steel mold to be processed rotates to the upper side, turn off the third motor (93). Then control the four electric telescopic rods (31) to reset so that the support grid (32) supports the tungsten steel mold again. After support, control the robotic arm (23) to work again to drive the grinding wheel (22) to move to grind the unpolished side of the tungsten steel mold; S4: After the grinding is completed, stop all power components. Then control the second motor (85) to reverse so that the two turntables (94) move away from the processed mold after grinding, and the mold can be unloaded; S5: During the grinding process, start the air extraction pump (73) to create a negative pressure environment inside the storage box (43). The spatter generated during grinding is filtered by the barrier net (45) and retained inside the storage box (43). After the grinding is completed, pull the pull rod (62) forward so that the two pull ropes (62) move to drive the two clamping posts (54) away from the two clamping holes (33), and then the storage box (43) can be taken out. After removal, the residue generated during the internal grinding process can be cleaned up.
